Malaysia’s national upstream company Petronas Carigali is forging ahead with its Kasawari giant sour gas field development offshore Bintulu, Sarawak.

Petronas next month will perform pre-installation survey services for the transportation and installation of the 8600-tonne Kasawari wellhead platform that was constructed by Malaysia Marine & Heavy Engineering.

Malaysia-flagged vessel Salvin Explorer has been chartered for the survey work, which is scheduled to start in mid-March and take around five days.

Dutch marine company Heerema Marine Contractors last year won a substantial sub-contract from MMHE for the transportation and installation of the Kasawari offshore structures – the central processing platform, wellhead platform, flare structure and two bridges.

HMC will execute the transportation and installation contract in two phases, starting with the wellhead platform later this year and the other structures in 2022.

Kasawari, located on Block SK 316 offshore Sarawak, is targeting production of 900 million cubic feet per day of gas. The field has estimated recoverable reserves of 3.2 trillion cubic feet of gas.
